Abstract

Volume polarization holographic recording in phenanthrenequinone-doped poly (methyl methacrylate) photo polymer is obtained. Photoinduced birefringence in a 2mm thick sample is measured by a phase-modulated ellipsometry. The birefringence induced in this material by linearly polarized beam at 514nm reaches 1.2×10−5. In addition, ability for recording volume polarization grating using two different polarization configurations is demonstrated and compared. The experimental results show that the diffraction efficiency of the hologram reaches to ∼40% by using two orthogonal circularly polarized beams.

The Bragg selectivity curve for a 2mm thick sample for a polarization hologram with diffraction efficiency ∼40%. The symbols represent measured results and the curve is theoretically fitted by using the coupled wave equation [6] .
